Prime Minister David Cameron has been accused of ignoring a “clear and unambiguous case” for him to attend a hearing with Parliament’s senior committee on the EU referendum.

The chair of the Liaison Committee – comprised of the chairs of Parliament’s select committees – made the claim in a letter written to Cameron.

Andrew Tyrie, chair of the Treasury Select Committee, has been engaged in correspondence with the Prime Minister in a bid to arrange a news hearing with the Liaison Committee since he last attended in mid-January.

However, Cameron told Tyrie in late March that it would not be possible to attend before the EU vote, set for 23 June.

Tyrie said that he was “surprised and disappointed” by the Prime Minister’s letter and urged him to reconsider, in particular noting a mid-March speech made by the Cameron in which he stated that the UK’s voters want to see arguments around the EU presented in a “calm and rational way”.
